Octopus-inspired deception and signaling systems from an exceptionally-stable acene variant

Area of Science:

• Organic materials science
• Photonics
• Robotics

Background:

• Multifunctional platforms with dynamic color modulation are crucial for diverse applications like displays, camouflage, and sensing.
• Developing camouflage systems with tunable spectral and fluorescent properties across UV, visible, and near-infrared regions is challenging due to conflicting material and device requirements.

Purpose of the Study:

• To create novel deception and signaling systems inspired by the Hapalochlaena lunulata octopus.
• To overcome the challenges in developing tunable camouflage systems with broad spectral coverage.

Main Methods:

• Incorporation of a stable, nonacene-like molecule as the active material in actuator-type systems.
• Development of devices featuring straightforward fabrication and multispectral operating modes.

Main Results:

• The active material exhibits exceptional ambient-atmosphere stability, surpassing comparable acenes.
• Devices demonstrate robustness, self-repair capabilities, and dynamic multispectral operation.
• The system offers a powerful combination of advantages for adaptive photonic applications.

Conclusions:

• The developed system provides new opportunities in functional organic materials, reconfigurable soft actuators, and adaptive photonic systems.
• This research offers a promising approach for advanced camouflage and signaling technologies.
